I'm having extreme trouble doing these problems. Could someone please help me out. Step by step.

Write each quadratic function in vertex form, if not already in that form. Then identify the vertex, axis of symmetry, and direction of opening.

1. Y= (x-2)^2

2. Y= -x^2 + 4

3. Y= x^2 - 6

4. Y= -3(x + 5)^2

5. Y= -5x^2 + 9

6. Y= (x-2)^2 - 18

7. Y= x^2 - 2x - 5

8. Y= x^2 + 6x + 2

9. Y= -3x^2 + 24x
